To allwhom'itmayconcem: j

Be it known that I, WILLIAM` EDWARDY residing at Chicago, in the county of.C'ook and State of Illinois, have 4invented new and useful Improvements in Automobile- Horns, of which'the'. following is a full,y

My invention. relates to hornsor warning signalsffor automobiles, and the like, adapted to be connected withthe exhaustport of theengine ormotor so that lwhen the gases expelled vtherefrom pass across 'the reeds of said .horn a chord will besounded for the purpose lofa' warning. j

It is the object of 'my invention to construct a signa-1 horn in such a mannerthat lno matter how high the pressure maybe in gine the reedsof the horn will notbe caused to shriek, butalwaysbe of a uniform pitch.'

It is also an object of my inventionv to arrange the* parts in as economical a mansirnply thatthe carbonized particles of com- This I accomplish bythe means and in the manner hereinafter fully described and as more particularly -pointed out in the where1n:- 'Figure l is a longitudinal side elevation of my improved horn orsignal. Figl 2 is. a vertical longitudinal. section of thel same taken through Vits axial core and showing the relative arrangementA of the various parts. Fig. 3 is a transverse vertical section thereof taken on line' 3 3, Fig. 1. y Referring -to the drawings, 1 is a suitable cast-metall coupler 'or head that "is preferably cylindrical or cup-shaed and screw-` threaded interiorly. The c osed'end of this forming a vpart hereof,

so'as to form a shoulder "2 andhasa central or axial'stub 3 that extends beyond the same. This coupler is Jadap'ted to be screwed' onto or otherwise .secured tothe A plurality of nozzles 6, 6, (preferably four.

` and project beyond thesalnea suitable dis' tance'. 'These vnozzles are vcylindrical in To Eamonn 'MANUFACTURING .coMrANm .oFeHIcAGc shape at their inner ends andscrew-threaded while their outer ends are tlattened to provide wide discharge orifices 7, 7,'t'hat project into the open end of the respective tubes v forming the: horn.l The stub 8 is bored out and .screw-threaded 'uponits in -l terior and an elongated rod 4 is tapped therein and 'secured in position'. lThis rod forms the core oraxis around which va plufrality of cylindrical-shaped fluid pressure" cured to the rod-and to each other andare' closed at their' outer ends,- their inner ends 'tubes 5a 5, of various pitches are secured.""`

These tubes are soldered or otherwlse Se; .y

being adjacent the coupler l. Said.v tubes arev ofditferent lengths in o1derto`jobtainz varying higlr and 'low pitchesV representing certainntes of the chromatic scale, and the nozzles 6 vprojecting therein are of various/fl lengths being longer or lshorter according to the tube into which they respectively project, the: longer nozzle registering with vthe short high pitch tube. Adjacent ythe 'nozi` zles, the side-walls ofthese tubes are pref-- erably cut away :to forni openings 8, and this ls'done by cutting va lT-s'haped slit in the end edge of said tube and bending the wings 9, 9, formed 'thereby backward upon the tube, as shown. The cylindrical portion of the tube just beyond il'swings is preferably flattened so: as to'present -a straight edge 10 against which the exhaust gases from the m'uiiier will impinge as they pass out ofthe discharge orifice 7 of the nozzles vand rsaid'nozzles are so arranged that said exhaust Will strike exactly at the straight edge 10, and `sound a note of a dif` ferent pitch in each tube. y'In order to more securely mountthe tubes Vin position, small studs 11, 11 arevformetl on the edge of vthe stub 3 landl in'arranging the tubes the segment thereof nearest to .the core i isp'laced so-as to engage one of-.said studs 11. A

plate orwasher of suitable dimensions and having openings through which these studs pass `is -seated between the end' edge. Iof the tube andthe face of the stub 3, as shown, and insures the proper .relation bei-,-

tween the parts, as well as regulates to a- 7 certain extent" the tone of, each tube. By the arrangement above f-described, :while the tubes are closed on their outer ends .their inner ends are openand'free and it'has' l been foundthat, no matter how high may be the pressure oi. the exhaust, the tone of each Will be uniiorm and -will not shriek andthe 'chord sounded, while pleasant to the ea'r'will besumciently 'violent to alarm and Warn pedestrians' and others of the approach of ticular arrangement and. number of parts it of course is obvious that the same may be varied according'to the needs of particular cases, vand lall such 4modifications are to be understood. as contemplated within the scope 'the vehicle.

While I havedescribed and il-shown a par- What I claiml as new -is 'f y1. A horn'comprisingxa .suitable coupling,

the outer endof 'which isfreduced in diameter {and ,forms a shoulder, a lurality of studs onthe end of said reduce portion, a 'pluralitylof cylindricalflud pressure tubes arranged around a` central core having open ends the edges of which engage said studs, cut-away vportions in the ends ofsaid tubes adjacentv said coupling, anda plurality ofA nozzles tapped throughpthe shoulder in said coupling tangential to the axis thereof and intersecting the edges of said cut-away porL tions.-v 2. Ahorn comprising a suitable coupling, the outer- 'end of Whichis reduced in diam eter and forms a. shoulder, a pluralitygo s'tud'son the end of said reduced portion, a plurality. of cylindrical fluid pressure tubes -arran ed around a centralc'ore having open ends -t eedges of which engage lsaid studs,

cut-away portions in Athe ends of said tubes -adjacent said coupling, and a plurality of said coupling and cut-away portions `therein, y and a plurality of nozzles tapped through said shoulder tangential tothe axis of said coupling and intersecting the edges of said' cut-away portions.

4.. A' horn comprising a' suitable coupling,

the outer end of which is reduced in dialneter and forms a shoulder, a plurality of -studs onv the end of said reduced portion, a

central core tappedint said reduced portion, a plurality of cylindrical fluid pressure vtubes arranged around said core having open ends adjacent said coupling that engage said studs and have cut-away portions in theirv ends, and .a plurality of nozzles tapped through said'ishoulder tangential to the axis of said coupling and intersecting the edges of said cut-away portions.

In Witness whereof I have hereunto set my hand this 16th day of March 1911.
